Four-part fix for the collection bottleneck that was blocking the dev loop:
1. Lazy mitreattack.stix20 import in attack_stix.py — deferred to first
_load() call (TYPE_CHECKING guard at top level)
2. Lazy misp_stix_converter import in both MISP export routers — moved
from module level into the route handler body
3. Lazy attack_catalog / attack_stix in ttp.py repo mixin — thin wrapper
functions so the import chain never fires at module load time
4. tests/api/conftest.py — `from decnet.web.api import app` moved inside
the `client()` fixture; `pytest_ignore_collect` broadened to skip all
test_schemathesis*.py variants (not just test_schemathesis.py), which
were launching a subprocess server at module-import time
5. pyproject.toml — `norecursedirs` for tests/live, tests/stress,
tests/service_testing, tests/docker, tests/perf so these directories
are never entered; `-m` filter removed from addopts (now redundant);
`--dist loadscope` → `--dist load` to unblock workers immediately
6. behave_core / behave_shell rename — BEHAVE packages dropped the
`decnet_` prefix; reinstalled editable installs and updated all 14
import sites across profiler, ttp, bus, and correlation modules
BEHAVE-EXTRACTOR.md Phase A Step 0. Lays the package skeleton
(__init__/extract/_parse/_ctx/_thresholds/_features) with empty
FEATURES = (), so the worker plumbing in BEHAVE-INTEGRATION Phase 4
has a stable import path before any primitive lands.
extract_session() builds a SessionContext once and fans the
registered feature functions across it; at Step 0 that fan-out is
empty and the function yields nothing. Step 1 (asciinema parser +
paste-burst detector) and Step 2 (motor.input_modality) land next.
Smoke suite asserts the empty contract: empty stream → no
observations, single event → t_start == t_end, multi-event → events
routed into input_events / output_events by kind, evidence_ref
defaults to "session:<sid>" or honours an explicit override.
